It's a replica Isamu Noguchi coffee table. It's a bit stereotypical 1980s yuppie to be honest (fits with all the 80s B&O I have!) but I like it!
You can buy official versions which cost £2k+, but I bought mine brand new for about £170 plus shipping from an Ebay seller
!! It's probably made in China but it seems to be good quality, solid wood base with a very heavy (I know because I dropped it on my toe once!)2cm thick glass top. I doubt you could tell much difference between a replica like mine and an original, certainly not £1800 worth of difference anyway!
There are loads for sale on UK Ebay from different sellers, and I'm sure the same will be the case in Aus. Just search Australian Ebay for 'Noguchi coffee table' and I'm sure you'll find one.
